Injection moulding

Process description:
Injection moulding is a discontinuous, multi-stage manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials.

Typical end products:
High volume end-consumer products. For example: caps, closures, automotive parts, and packaging. It is a part manufacturing process and is not based on lot sizes i.e. weight.

Process:
The raw material is fed into a heated barrel, and with screw is mixed and forced into a mould cavity. Once the plastic has cooled and hardened the mould opens and the part is ejected.

Typical materials being processed:
Most granular raw and compounded polymers, including all thermoplastics, some thermosets, and some elastomers. In addition regrind materials and additives.

Description of motan system/equipment used:
Complex centralised or stand alone drying, conveying, dosing & mixing systems. Typically for the automotive, electronics, household-goods, medical and packaging industries.

Typical dosing & mixing units:
Additive dosing units (MINICOLOR, COLORBLEND) or Gain-in-weight blenders (GRAVICOLOR, ULTRABLEND).
